I really enjoyed this mystery set in London in 1924. I read a review of it in The Sun but it wasn't available in the library so bought a Kindle edition on Amazon. I loved the setting and the WW I background and it is a well developed plot. Good summer reading for my friends who enjoy mysteries.
It seems it is published by a company called Inkshares and it looks like it's going to be developed into a TV series.

I wish the author the best of luck and look forward to reading more.
About the author:
My name is Christopher Huang. I grew up in Singapore and moved to Canada when I was 17. I returned to Singapore the following year for two years of military service, before going to McGill University in Montreal to study Architecture. I still live in Montreal; these days, I’m pursuing the dream of writing full-time.
I’m a longtime fan of the "golden age" of detective fiction, and the principles of fair play governing the genre, as described by Ronald Knox in his decalogue. As Ellery Queen observed, the primary attraction of detective fiction is that the reader should be able to solve the mystery themselves from the given clues, prior to the grand denouement.
